WinnieThePooh: “Each citizen has a gas mask kit just in case, that is updated every few years.”
BTW – The gas masks were all recalled a few years ago. Noone has them any more.
As for the siren system, as you mentioned earlier – they only sound if there is reason to believe that something will land in that area. There are times that Missiles are fires and no siren is sounded because with all the detection there is, they know that it’s not near a populataed area.
